This role requires a true proxy engineer — someone with hands-on experience of SWG platforms who can translate policies, troubleshoot traffic flows, and own the migration workstream rather than follow scripted procedures.
Key Responsibilities
* Lead and deliver Secure Web Gateway migration activities from Skyhigh to Blue Coat
* Translate and rebuild proxy policies, SSL inspection rules, and exceptions
* Troubleshoot authentication, traffic flow, and policy issues during cutover
* Work closely with network teams to manage traffic steering and proxy routing
* Support testing, validation, and optimisation of the new proxy platform
* Own assigned migration workstreams end-to-end
Required Technical Experience
* Hands-on experience with Skyhigh Web Gateway and/or McAfee Web Gateway (MWG / CWS)
* Hands-on experience with Blue Coat / ProxySG / Symantec / Broadcom
* Strong understanding of Secure Web Gateway / proxy architectures
Experience with:
* PAC files
* SSL/TLS inspection and bypass
* Proxy authentication (Kerberos / NTLM / headers)
* Explicit proxy traffic
* Proven ability to troubleshoot proxy traffic at depth
Supporting Infrastructure (Desirable)
* F5 or AVI load balancers
* Fortinet firewalls
* Bluecat DNS
* Enterprise network environments
Key Attributes
* Highly technical and hands-on
* Able to work autonomously and own delivery
* Comfortable operating without step-by-step runbooks
* Experience in regulated or large-scale enterprise environments preferred
